Four O' Clocks, but some consider it invasive. They have a very nice fragrance, I like them and have them. My Zinnias stay open all the time, so do the roses, the Cosmos... Almost everything in the garden, what kind of flowers do you have? I can only think of 3 that aren't in bloom in the late afternoon, the Mexican Petunias (invasive), Daylillies, Morning Glories.

I do have Mexican Petunias, they came w/ the house and I do like them. we bought the house last july and in the year the Mex Petunias have not "gone" anywhere, they have gotten leggy ( i think that is the term) but I did not cut them down during the fall/winter and right now I just love that they have flowers every day so I cant bare to prune them now, but I will once I notice less flowers!

I have Blue daze and they seem to close at night - well I think they "die" I think the flower is a 1 flower a day type thing and maybe the same about the Mex-P.

I have two Gaura (light and dark pink) but they seems to stay open, but they are small so I think when I look at the space I notice the closed looking flowers more then them (but I love them - hope they continue to grow and attract butterflies - I have a black mothy butterfly that hangs out in the Gaura).

I have a cucumber plant that has flung it's self out of it's lil pot, I fear I should not let it hang out w/ the other flowers, but it too have lil yellow flowers, so I have not moved it. It was just something my son did w/ the neighbor kids, we did not think the seeds would grow or that it would still be alive. I dont think it will stay, but I have not moved it (not sure what I should even do with it)

I have Aloe that is in bloom. I was thinking of moving them in the future, but now that they have bloomed (they did not do that last year when we 1st got the house) I think I will keep them there a little longer.

It is just a small space that only had the Mex - P and the Aloe, so I added the Daze and the Gaura just based on looks and price. I am slowly adding more things in and that is when I thought I should make a conscious effort to find something that likes the evening so I have pretties to say hello to when I get home.

in the front yard I am doing a tropical thing, so they are open all day/night, but in the back I want a lil flower/butterfly area.
